1 Claim.

This invention relates to the head for a spool, reel beam or beamhead ofthe type used for reeling wire or textile material.

In the manufacture of heads for spools, reels and the like, it has beenfound desirable to strengthen the outer peripheral rim of the head invarious ways. ierent thicknesses may be obtained in the head forstrengthening the same. In sheet metal heads with which this inventionmore particularly deals, the strengthening of the outer peripheral edgeof the head has sometimes been done by flanging or curling the peripheryoutwardly with all thicknesses of the stock of the head remaining thesame. In some cases separate pieces of material have been added to theouter peripheral rim. Several of these constructions materially add tothe weight of the head which is undesirable. In some cases the outerperipheral edge of the head has been strengthened by increasing thethickness of the stock such as shown in Patent 2,286,640, dated June 16,1942.

One of the objects of this invention is to increase the rigidity of thehead, especially at the outer peripheral edge thereof, while keeping theweight of the head to the minimum.

Another object of this invention is to increase the rigidity of the headat the outer peripheral edge thereof by forming the stock in such amanner that it is formed in two plies in contiguous relation so onesupport the other.

Another object of this invention is to provide a tubular section curlededge having the stock of the tube cross section extending greater than360 degrees to provide overlapping strengthening portions either byutilizing a single ply of the stock or two plies formed together forthis purpose.

With these and objects in view, the invention consists of certain novelfeatures of construction, as will be more fully described andparticularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1 is a perspective view of a spool or reel constructed inaccordance with this invention;

Figure 2 is an elevation partly broken away and in section showing theconstruction of the barrel and head;

Figure 3 is a fragmental sectional view of the edge of the head; and

Figure 4 is a iragmental sectional view illustrating a modified form ofthe edge of the head.

In proceeding with this invention, I form the Where the heads are cast,difouter peripheral edge of the head in a spiral fashion so that itextends through more than 360 degrees with the portions which extendbeyond the 360 degrees in contiguous relation so that one supports theother, or I may use two plies of material, such as shown in Figure 4,oppositely formed and nesting one in the other with a portion of onesupporting the other, so that a two-ply relationship support is alsoprovided.

With reference to the drawings, it designates the barrel which isprovided with heads I! at either end thereof. These heads have centralportions extending inwardly as at I2 in end-toend relation as at l3 withthe barrel and are welded at the joint.

A center tube [4 is supported from the heads H by thereenforcement l5which is bulged outwardly as at .16 and returned inwardly as at I! to beoverlapped by the ends'of the center tube M as at [8 and secured theretomechanically by flaring or by welding.

The outer peripheral edges [9 of the heads H are strengthened and maderigid by forming the stock outwardly and then inwardly into a spiralcoil as at 20, so that the inner portion 21 of this coil will contactthe head forming two plies of stock and a very good support for therolled edge of the head. In effect, there is a tubular formation aboutthe peripheral edge of each of the heads which gives a very strongconstruction and a very rigid construction to resist bending when thespool or reel is dropped or receives a severe blow.

In some cases, as shown in Figure 4, the stock of the peripheral edge ofthe head II, which is now designated 'as 22, is formed inwardly anextent less than that shown in Figure 2, and in this case thereenforcing plate [5 extends outwardly of the head H and is curledinwardly as at23 to an extent so that its inner end 24 is in line withthe plane of the reenforcing plate l5. In this manner, there is areenforcement of the curled edge of the head ll throughout a largeportion of its extent, and a closed loop or tube is provided extendingaround the edgeof the head which provides a very rigid and strongconstruction.

By this arrangement, a head is formed which provides a very rigid andstrong outer peripheral edge and the stock is all of the same thickness,being reenforced by double plies of the stock formed by the overlappingcurls, either from a single piece of spiral formation Where the partsoverlap beyond the 360 degree curl or by forming the same of two pliesand oppo- References Cited in the file of this patent sitely cur1ingthem so that the same two-ply UNITED STATES PATENTS stock 15 provldedfor reenforclng purposes.
